17270222 02 ml; fl M MM; lllllllll and this necessarily produces a very severe strain, which in prior brakes of ing this support may be employed to secure this effect, but with the motor arrangement shown this support is conveniently secured by mounting the rock-shaft 15 on the distancerod 7. Inasmuch as this distance-rod is supported at one end from the axle and at its opposite end from the motor-casing, which in turn is connected to the body of the the strain due to the braking of the e in the form of approximately a vertical load. Such a load the axle is well adapted to bear, and the springs are left entirely free to has occurred with former devices of this kind.

In order to keep the brake-band 11 from sagging,so as to rest against the brake-drum when released, I provide a supporting-arm 20, secured to the distance-rod 7 and extending around the axle to the opposite side of the brake-ring. The outer end of this arm is reduced in diameter and into an opening formed in a lug 21 on the brake-ring. The brake-ring therefore is supported at approximately two diametrically opposite pointsthat is, at the point 21 and on the rock-shaft 15. The end of the arm 20 fits loosely in the opening in the ring and projects practically radially of said ring, so that the reduction of the diameter of the ring, which ring except when it is deslred to apply the latter thereto. The sprocket-wheel 10 is connected to the wheel-spokes by detachable clips 22.

My improved brake can be applied to vehicles of all kinds and not merely to motor-vehicles such as shown, it merely being necessary to support the brakeringthat is, the rock-shaft 15-from suitable rods or the like hinged to the vehicle-axle and vehicle-body, preferably two such rods being used, one taking the place of the motor-casing 5 andthe other of the-distanee-rod 7. Vehicles other than motor-vehicles which with a sprocket-wheel can have a brake-drum attached to the wheel-spokes by means of detachable clips, such as are shown for attaching the sprocket-wheel thereto, and the brakeband will operate on this drum.

is applied as close as possible to the rim of the vehicle-wheel, so that it operates radius and produces a very severe braking l effect. The strains produced thereby, however, are transmitted directly to the axle of the Vehicle, so that they brake-drum on all sides.

What I claim as my invention, and desire to secure by Letters Patent, is

In a motor-vehicle brake, the combination with the vehicle wheel and body, motor suspended from the body by a hinge connection, gearing between said motor and the wheel, means for holding saidmotor an distance from the expanding ring arranged to engage said drum, means for expanding said ring, and an anchor for said ring supported from the motor.

2. In a vehicle-brake, the combination with the vehicle wheel and pended from the body bya hinge-joint, a disgaging said connected to said distance-rod.

3. In a vehicle-brake, the combination with the vehicle wheel and body, of

side opposite In a vehicle-brake, the combination with the vehicle wheel and body, of a motor suspended from the body by ahinge-joint,'a distance-rod hinged to said motor and to the vehicle-axle, a brake-drum arranged to rotate with said wheel, an expanding ring for engagthe axle an wheel, of

rotating with said my brake the braking strain 5 on a long support to the opposite side of the ring and having a sliding connection therewith.

7. In a vehicle-brake, the combination with the axle and Wheel, of a brake rim or drum rotating with the wheel, an expanding ring arranged to engage said drum, links connected to the open ends of said ring, a swinging lever to which said links are connected, a support from the vehicle-axle in which said lever is mounted, and an arm connected to said support 1 and extending to the opposite side of the ring with its end in sliding engagement therewith. In testimony whereof I, the said HIRAM PERCY MAXIM, have hereunto set my hand.
